India and Pakistan have issued a joint statement after the first meeting of an anti-terrorism panel.
The fact the talks took place is seen as progress
It says the sides agreed the guidelines of how the mechanism will work.
The tone of co-operation does not reflect earlier frustrations expressed by Pakistani officials disappointed at what they called a lack of progress.
This was the first time the regional rivals had held talks about fighting terrorism together, and that in itself was seen by many as a step forward.
The brief statement says the two sides agreed to exchange specific information that could help ongoing investigations or prevent terrorist attacks.
It says the anti-terrorism panel will meet four times a year, but the two heads of the mechanism can directly discuss any urgent issues.
Pakistan had been hoping to hear more about India's investigation into the firebombing of a train last month which killed many Pakistani passengers.
Officials said the Indians only gave them the sketch of a suspect, said to be from Pakistan.
They said the Pakistani side handed over a dossier with specific evidence showing that Indian security agencies were involved in terrorist acts in the province of Balochistan.
